Can you explain me the difference in using 하는게 좋다 and 하는걸 좋아한다 ? If both mean " I like doing", I don't really know when "doing something" can be consider as an identifier particule or as an object one. Your example are both similar so in my mind it's a bit messy.

Hello!I have such question,could you answer, please?For example,if I have the word '생각하는건' so its meaning will be 'thinking',right?So the part '건' is also some contraction like from '것은',or no?Thank you ~
